Okay, the Subject line is the problem in a nutshell.
I have not one but two Outlook.com accounts. Both are working fine and I can access them via both the website and the Outlook.com Android app. This continues to be true even after a recent password change in the 2nd account.
(Separate issue: I *much* preferred the way things used to be when Outlook.com let me keep these accounts separate. But now, MS thinks they know besat and know what's right for me and will NOT let me keep them apart, insisting that the "better way" is to set up the 2nd one as a Send Only account and forward it to the 1st account. BTW, I am not entirely certain this isn't at the root of the problem I'm having with WLM).
However, with the password change has come a problem with my desktop computer's (Win 7) installation of Windows Live Mail: it continues to access all of my email accounts including the 1st Outlook.com account but NOT the 2nd Outlook.com account (the one with the password change and the recent MS-initiated change to a Send Only account). WLM keeps asking me to log in to the account as if the user name and password are incorrect. Both are, in fact, quite correct...even to the point of using copy-and-paste on the password out of the functioning Outlook.com web interface.
Any idea what's going on here?
